THE age-old dilemma of how to fit a round egg into a square sandwich has been resolved – by a gadget that turns the food into a cube.

The handy device, known as the Egg-Q-Ber, is a square-shaped jar into which a hard-boiled egg is placed.

The user simply cooks the egg, peels off the shell, puts it in the container and then screws down the lid, which forces the egg into a cube shape.

After just one minute, the egg is ready to be sliced – fitting the sandwich exactly.
